I am beginning to appreciate the difference between knowledge and wisdom. Knowledge is information which someone is aware. Knowledge also means confident understanding of a subject, the ability to use information for achieving a particular purpose. In dentistry, we have lot of very knowledgeable people. People gain knowledge through learning and education. Knowledge is tangible. Knowledge changes over time. Wisdom on the other hand is the ability to make correct judgments and decisions. Wisdom is an intangible quality gained through experience. Wisdom is timeless.
